First flown in 1931, the Grumman FF-1 (affectionately known as "Fifi )" was noteworthy for its innovative design characteristics that marked a great step forward in aircraft design - first fighter with retractable landing gear; an enclosed canopy for both cockpits; and, an all metal, stressed skin fuselage. The "Fifi" was of rugged design typical of all future Grumman aircraft. The single significant drawback to the FF-1 was its poor climb capability, taking six minues to reach 10,000 ft. The FF-1s entered service with the fleet in June 1933 with delivery to VF-5B, the only squadron to ever operate them. They were withdrawn in November 1935 and relegated to reserve duties. A later model (FF-2) was configured as a trainer with the installation of dual controls and operated with Marine Reserves. By 1941 only two remained in service. Mahogany Wood. Scale: 1/24.
